The T-37 was a Soviet amphibious reconnaissance tank developed on the basis of the British Carden-Lloyd tank. Several test versions of the tank were built (T-33 and T-44 ); mass production under the designation T-37 began in autumn 1933.
Development and production
The T-37 light main battle tank was developed by chief designer NN Kozyrew (and, after his arrest, Nikolai Alexandrovich Astrov ) and went into production in 1933. By 1936, a total of 2627 units were built in Plant No. 37 (Sawod No. 37) in Moscow .
T-37: The first version of the tank had serious flaws - the riveted outer shell was not waterproof. Only 70 pieces of this version were produced.
T-37A: The outer shell has been redesigned to ensure watertightness. The riveted cover was replaced by a welded one. About 2,600 of this version were produced from 1933 to 1936. The armament consisted of a 7.62 mm machine gun . The tank was only used for reconnaissance purposes in poorly defended areas.
Use in the Wehrmacht
Captured T-37s were mostly used by the Wehrmacht under the designation 731 (r) in security units in the occupied hinterland of the Soviet Union or as tractors. When used as a tractor, the tank turret was often removed. Infantry units also use the T-37 as a reconnaissance vehicle. Air force security units for airfields also use the T-37. German units partially replaced the tank turret with German machine guns or 2 cm machine cannons with a protective shield.
